    Default Measuring the power output of the laser tube

    I bought a 60W laser tube for a DIY laser that I built, but I'm not convinced that it is getting anywhere close to 60W.What is the best / cheapest way to check the power output of the laser?

    One of the links placed at the end of your request is labeled "Laser power meter for testing laser tube power"

    It leads to this product. https://www.aliexpress.com/item/High...809985313.html

    I saw this. $312 seems expensive for what I'm trying to do. I don't need to know +- 0.1 W. I just want to know if this thing is producing like half of the 60W it is supposed to. I'm wondering if there is a problem with the power supply. I think it might really be a 40W power supply.

    Have you contacted Russ at SarbarMultimedia on YouTube? He created what he calls a "Dohickey" that can measure laser power output. Not sure if he still sells them, but it might be worth asking.



    You can also buy a Macken Instruments laser probes on eBay for around $120-150.

    I have a 50W epilog helix and I cut 1/8" thick baltic birch plywood with the following settings;

    Speed = 16% = 80in/sec*.16= 12.8in/sec
    Power = 93% = 46.5W
    Freq=500Hz

    You could use this as a basic benchmark to check your machine.

    Try to found someone near you with power meter. Cheapest.
    Buy simple power meter - bit more expensive, but way better.

    Most ebay/chinese 60w laser tubes are rated for peak not continous power. What is make/model/length of your purchased tube. What current are you running the tube at? What voltage and what power supply. These all will effect the output power of the tube. Before even trying to check output power make sure you are running your tube at the proper parameters.

    I am measuring 21.3 mA.
    I have the power supply set to 110V.

    The tube is 1200mm, 50 mm diameter.

    Follow robertk925's advice. Russ' device costs less than $70 to put together and works great.

    Measure both at the end of the tube to find out the tube's actual output and then again at the work surface to find out how much loss you are getting via your mirrors.
